What it is and where it sits in the Sabre series
The Molex 431601104 is the 4-circuit member of the Sabre 43160 series — a single-row, right-angle power header with male blade contacts that mates with the matching Sabre receptacle housing. The 7.50 mm (0.295-inch) pitch places it in the mid-range power class — larger than Micro-Fit but tighter than Mega-Fit — suited for wire-to-board power distribution where board space and current density both need to be managed. The locking ramp on the housing side provides audible and tactile mate retention, which matters in any application subject to vibration or cable pull. Tin plating at 60 µin (1.52 µm) is the standard shelf plating for this series; it is adequate for the stated 18 A per circuit at room temperature and supports the normal mating-cycle range for a tin-finish power interconnect.
What the buyer came for — fit confirmation
4 positions, 7.50 mm pitch, right-angle through-hole, male blade — if those four facts match the BOM line, the 431601104 is the part. The black insulator colour does not affect function; it is a visual aid for colour-coded harness positions. Bulk packaging means loose pieces in a bag — confirm that matches the assembly flow. The header mates with the corresponding Sabre 43160 receptacle housing and the appropriate Sabre crimp terminal for the wire gauge the application calls for.
